Electricity Generation
Self-generated electricity for free use on-site or to sell on!
If you already employ or are planning to use a waste incineration plant as part of your daily operations then you should investigate how we can assist you to harness the heat produced as part of the combustion process to generate what can be substantial levels of electrical power.
This self-generated electricity can then be utilized as a ‘free’ power source for your own on-site operations, while any surplus electricity can be sold at profitable rates to an off-site electricity grid provider.
Depending on the scale of your incineration operation we can include or retrofit two different types of electrical power generation technologies. It is only by speaking to you and evaluating your incineration process that we can advise on the viability of the scheme and forecast the expected earnings that our energy recovery systems could generate for you.

Organic Rankine Cycle (ORC) Hot water to power
ORC technology is more suited to smaller incinerator plants. It utilizes hot water generated from the heat exchanger incorporated in the waste heat recovery phase of the process that is passed to a heat engine and this in turn powers a generator set to produce electrical output.
The process is approximately 6 to 10% efficient (process temperature dependant) in converting the thermal energy in the water to electrical power.
If we install a new waste heat recovery plant then the process temperatures in the heat exchanger will be configured to reflect the higher efficiency.
This technology, when retrofitted to an existing plant, can offer a self-payback of typically between 3 to 7 years subject to the energy value of the waste.
Maintenance costs are extremely low (circa 2% of ORC cost per year). -
Steam Turbine (Reaction Type) Superheated steam to power
This technology is especially suited to larger incinerator plants. It utilizes high pressure superheated steam generated from a steam boiler/super heater in combination with an economizer that is passed to a steam turbine and which in turn powers a generator set to produce electrical output.
The process is approximately 20 to 22% efficient in converting the thermal energy in the steam to electrical power.
This technology can significantly reduce the turnkey installation payback period for a WID/IED compliant W2E facility to typically between 2 to 5 years subject to the energy value of the waste.
Maintenance costs are low (circa 1.5% of turbine cost per year)
We are always available to discuss the viability of your existing incinerator or cremator plant or to advise on feasibility and how best to accommodate electricity power generation into the specifications of your new incinerator or cremator.
We will also provide free Return on Investment analysis as part of our appraisal.
